Electronic cigarette cartridges are available in various strengths so you will have to visit their site to get the official amount of nicotine they contain. However the following sort of seems like it is the standard in the industry this far.

16mg per refill cartridge – This is about the same as a full flavor traditional cigarette. Some companies even call this a red due to its similarity to Marlboro Reds.

11mg per refill cartridge – This is about the same as a medium traditional cigarette. So if you smoke anything like Marlboro Mediums then this is the equivalent of nicotine you are used to taking in.

8mg per refill cartridge – This is about the same as a light traditional cigarette. So if lights are your thing the 8mg cartridge will be a good place to start.

4 mg per refill cartridge – This is about the same as an ultra light cigarette. If you got this far congrats now you just need to quit. Why not stay with these or even try a zero nicotine cartridge and quit completely!

0mg per refill cartridge – These cartridges are made available by most electronic cigarette companies. They contain zero nicotine so you are simply just inhaling the flavor and glycol. At this point you are literally not smoking or taking in any nicotine. Congratulations!
